Application filed July 14, 1910. Serial No. 571,938.

. To all whom it may concern:

Be it known that we, HENRY P. KRAFT,

residing in Ridgewood,'in the county of Bergen and State of New Jersey, and PHILIP WV. KAUTZMAN, residing in West Hoboken, in the county of Hudson and State of New Jersey, both citizens of the United States, have invented certain new and useful Improvements in Tools for Looking and Opening Split Rims, of which the following is a specification.

This invention relates to tools for manipulating pneumatic tire rims.

It has heretofore been proposed to con struct a rim for pneumatic tires in two sections', which sections are provided with interlocking lugs or similar devices which require a rotary movement of one part relatively to the other in order to lock them toperform the operation of locking and ungether. WVith a heavy rim and the necessary friction between the parts it has been found diriicult in certain cases to manipulate the parts by hand.

The object of the present invention is to provide a tool which will easily and quickly locking the rim sections. 7

Referring y to the drawings 1n WVlllQll we have illustrated one form of our invention,-

Figure 1 is an inner side view of a, rim of the type referred to showing the tool -in operativeposition. Fig. 2 is a section on the line 22 in Fig. 1. p

In the drawings let A indicate a pneu- I matic tire rim composed of two sections B and C. In the construction shown the sections are adapted to be held together against lateral displacement by hooks D formed on one section "and engaging lugs E formed on the other section. In order to engage the lugs with the hooks, the section B for instance is placed upon the section C with its hooks in the dotted line position and one or the other section is rotated relatively to the other in order to engage the hooks and lugs. This construction'is one example 1 of a rim to which our improved device is applicable, although the invention may be modified to operate upon other constructions of rim. v

In the construction shown the device includes a tire manipulating means such as the lever F adapted to bear againstone sec tion of the rim, and means for temporarily connecting said lever with the other section of the rim or a part carried thereby. In the construction shown we providea plate G upon which the lever F .is mounted at H, and this plate G is adapted to fit over a block J connected to the section C of the rim. Preferably the plate is provided with a recess and is adapted to embrace the block J, the edges of the plate and block being correspondingly beveled as shown in Fig. 2,

' so that the plate cannot slip. out of engage ment with the block. The pivotal point H of the lever F is preferably arranged at one side of the block J, and the lever is adapted to operate upon the hooks D, preferably to both engage and disengage the hooks. To

this end it is desirable to provide the lever with a pivoted block K which is so formed that on one side it will engage the end of one of the hooks without engaging the lug E and on the other side will engage the base of thenext adjacent hook. To this end the pivoted block K is provided with a narrow bearing surface L at one end and with a broad bearing surface M at the other end. Furthermore, the block is arranged to slide along the edge of the plate G so that it is' guided in its movements and always strikes the hook D at the proper point.

In Fig. 1 of the drawings the tool is with relation to the hooks and lugs. k The plate G is best made considerably wider than any rim in use so that its lower edge N will rest upon the floor or "ground when rotating said m the tool is in use. This will elevate one side of the rim slightly above the ground and force the plate (1 against the hooks. H the plate G were of less width, than the rim, it would be apt to slip clown in use and throw the pivoted block K out of operative relation With. the hooks D.

In use the rim section C is laid flat upon the ground, the tire inserted in place and the upper section B applied to the lower sec tion. The plate G of the tool is then slipped into engagementwith the block J and by a single movement of the handle the section B of the rim is rotated until the hooks D ongage the lugs E, The rim. sections ma then be locked in any suitable manner. i l/ hen it is desired to remove the tire the tool is placed in the position shown in l? 1' and the lever F moved in the opposite direction, whereupon the reduced :t'ace L engages the end of the next adjacent hook and gives the rim section B e rotetive movement-in a direction to disengage the parts: The section B may then he lifted oil and the tire removecli While We have shown in detail one form of our device, it Wlll he ll'ilflfilStOOtl that -.We do not Wish to he li-mitecl thereto various modifications Within. the scope of the claims may be made therein Without (leparting from the invention. The form illus trated is best adapted for the type of rim shown, but for other types of rim suitable changes will be made in the'tool.
